The fish is commonly found in freshwater hot springs in Turkey, Jordan and Iraq, Chang said.
The fish has been used to treat skin diseases such as athlete's foot and erysipelas for more than 100 years.
According to Chang, the fish can grow to about 6cm in length and can live in water with temperatures as high as 36 degrees Celsius, although the most suitable temperature range is 25 degrees Celsius to 35 degrees Celsius.
The fish is easy to keep as it eats small animals and plants. Hundreds of them are often kept in the pools by hot spring owners in the region so that they will nibble away at the dead skin cells and bacteria around wounds on people taking a bath.
The Taitung Oceanarium has set up a hot water pool with several dozen hot spring fish in the entrance hall, and the exhibit has attracted many visitors.
Many people don't dare put their hands in the water at first, but once they do, they discover that the fish nibbling at the fingers is almost like a slight electrical sensation.
Chang also said that hot spring operators in Chihpen (知本) in Taitung County are planning to introduce the fish together with medicinal herbs in their pools in the hope that people with skin diseases will also be able to enjoy the pleasure of a hot spring bath.
